Abstract
Temperature dependences are studied of green upconversion fluorescence of the five erbium- and ytterbium-doped glasses (three fluorophosphate glasses, one of which is additionally doped with Tm, and two tellurite-baruim ones) in the temperature range from 30°C to 150°C. The ratio of intensities is determined of two fluorescence bands at about 515-525 nm and 540-560 nm versus the specimen temperature. The sensitivity of temperature measurement is found and a comparison of the glasses is performed according to this characteristic.
